Description

The lime and brick delivery pump

Technical field

The utility model belongs to the lime and brick conveying equipment, relates in particular to a kind of lime and brick delivery pump that is used for the building aspect.

Background technology

At present, the lime and brick delivery pump of China mostly is mini-plant, these equipment pressure are low, water/binder ratio is big, because of reaching almost, its structural performance and air-proof condition can not mix sand, so it is big to be sought after a kind of discharge pressure, pumped (conveying) medium water/binder ratio little (0.45--0.6), the equipment of pumped (conveying) medium sand coarse aggregate ratio big (1: 3.5).And this equipment must possess the discharge pressure height, good seal (high abrasion guarantees application life).We have designed this hydraulic pressure integrated oil path and sealing device especially at these two problems, make and all obtain huge raising in its service behaviour and application life.

Summary of the invention

The purpose of this utility model provides a kind of good seal, is difficult for making sealing and a kind of compact oil circuit that high discharge pressure can be provided of sand-lime leakage.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is:

A kind of lime and brick delivery pump, include frame, hopper is housed on the frame, the front end of hopper is equipped with discharge nozzle, the bottom of hopper is provided with the S pipe valve, one end of S pipe valve is connected with two concrete cylinders, the other end is connected with discharge nozzle, two concrete cylinders axially are connected pushing hydraulic jack with two, and be connected with the commutation oil cylinder of two radial fit, and the hydraulic control device that is connected with two commutation oil cylinders, the swinging axle that is connected with hydraulic cylinder passes hopper and places the S pipe valve in the hopper to be assembled together, felt and dust-proof seal ring are equipped with in the junction of swinging axle and bucket wall, and felt and dust-proof seal ring are fixed them and compress by axle sleeve; The junction of S pipe valve and bucket wall is provided with dust-proof seal ring and felt gasket, and by platen and flange they is compressed; Between S pipe valve and flange, be provided with and be used to prevent the nylon wear ring that weares and teares, as supporting the S pipe valve is swung by flange and nylon wear ring, the nylon wear ring compresses it by discharge nozzle, in order to prevent that feed back from entering the junction of S pipe valve and nylon wear ring, outside the nylon wear ring, also be provided with sealing ring.

Hydraulic control device is made up of electromagnetic valve I, electromagnetic valve II, overflow valve, flow speed control valve and hydraulic manifold block, described electromagnetic valve I is installed in the bottom of hydraulic manifold block, described electromagnetic valve II is installed in the top of hydraulic manifold block, described overflow valve is installed in the right side of hydraulic manifold block, and described flow speed control valve is installed in the front portion of hydraulic manifold block.

Owing to adopted better seal, make the utility model in use can not reproduce into the leakage of lime and brick, can prolong the application life of equipment like this.Hydraulic control device adopts integrated method, and each parts of regulator solution pressure-controlled are installed concentratedly, can save many connecting pipes like this, improves oil circuit pressure, has not only reduced volume but also reduced cost.
